After running these in my RX2/3 for 2 cycles per pair, I am satisfied so far with their authenticity."

"Took them to work and I use them in a Ultrafire wf-501b flash light and a Ultrafire wf-502b flash light. I am an auto tech by trade and use my lights at times upnto an hour. They are used all day everyday for inspection and to provide light when I need to replace a part."
"Batteries are great, knocking off a star as charger is odd, spring mechanics takes getting used to."
"Work as expected, preferred over the more expensive/ higher capacity ones, also they dim when they are towards the end- heads-up that you are approaching the end ( there are some that maintain the perfect power delivery until the totally crash - for my application, diving, this was a no-no) ."

"Also the charger works for smaller lithium batteries like for my Arlo camera batteries."
"The charger works as expected, however the metal sliders are hard to move and the design is very poorly made."

Find Best Price at Amazon"For the Amazon Basics batteries, the capacity at each discharge rate was: Disch Rt | Capacity | Runtime | Sample use case. 100 mA | 997 mAh | 10 hrs | Low-power LED flashlight. 200 mA | 914 mAh | 4.5 hrs | Electronic toy / medium LED flashlight. 400 mA | 623 mAh | 1.5 hrs | Motorized toy / bright LED flashlight. Note that these (and all other Alkalines) would achieve somewhat higher capacity (maybe 1200 mAh) in a low discharge application like a mouse, keyboard, remote control, etc because alkaline batteries have internal resistance that reduces usable capacity at high discharge rates. Their capacity results were: Disch Rt | Capacity | Runtime. 100 mA | 1005 mAh | 10 hrs. 200 mA | 864 mAh | 4.3 hrs. 400 mA | 670 mAh | 1.7 hrs. As you can see, the Amazon batteries were very comperable ... but, at the current time the AmazonBasics batteries are $0.31/ea (36 pack), while the ACDelco batteries are about $0.21/ea (48 pack) -- so the ACDelco are significantly cheaper per mAh. I ran the Rayovac test several times because I couldn't believe how poorly they did ... here are some typical Rayovac results: Disch Rt | Capacity | Runtime. 100 mA | 908 mAh | 9 hrs. 200 mA | 590 mAh | 2.9 hrs. 400 mA | 443 mAh | 1.1 hrs.

"One strong factor is that these claim to be made in Japan, and Japanese-made batteries from Panasonic, Sony, Maxell and other major name brands have a good reputation. The biggest change I understand is the shelf life of the newest formulation is now rated at 10 years.
